Coordinating the use of independent radio receivers associated with a single transmitter

ABSTRACT

A computer-implemented method comprises discovering, by a client device, an available host computing device implementing a radio receiver, wherein the host computing device is identified from a decentralized shared database; establishing, by the client device, a relationship with the host computing device based on discovering the host computing device from the decentralized shared database; receiving, by the client device, application data from the host computing device based on establishing the relationship, wherein the application data is associated with radio signals received by the radio receiver from a single transmitter; and storing, outputting, or displaying, by the client device, the application data.

BACKGROUND

The present invention generally relates to coordinating the use ofunrelated radio receivers and, more particularly, to coordinating theuse of unrelated radio receivers that receive radio signals from asingle transmitter.

Radio receivers, such as software defined radios (SDRs) are radiocommunication systems in which components that have been typicallyimplemented in hardware (e.g. mixers, filters, amplifiers,modulators/demodulators, detectors, etc.) are instead implemented bysoftware on a personal computer or embedded system. A basic SDR systemmay include a computer device (e.g., a personal computer, miniaturecomputer, mobile device, etc.) equipped with a sound card, or otheranalog-to-digital converter, preceded by some form of radio frequency(RF) front end. In an SDR system, significant amounts of signalprocessing are handed over to the general-purpose processor, rather thanbeing done in special-purpose hardware (electronic circuits). Such adesign produces a radio which can receive and transmit widely differentradio protocols or frequencies (sometimes referred to as waveforms)based solely on the software used.

SDR receivers are used in applications in which a wide variety ofchanging radio protocols and frequencies are required in real time. SDRreceivers are often individually owned and operated, and thus,coordinating the use of multiple different SDR receivers for variousapplications is complex, if at all possible.

As described herein, aspects of the presentinvention may include systems and/or methods to discover, negotiate, andcontract with radio receivers in order to coordinate the use ofunrelated radio receivers that receive radio signals from a singletransmitter. In embodiments, the radio receivers may be implemented byhost computing devices (e.g., portable computing devices, miniaturecomputing devices, mobile computing devices, etc.). For example, a hostcomputing device may include an integrated or external peripheral radioreceiver. The radio receiver may include SDR receivers and/or othertypes of radio receiver.

In embodiments, independent and unrelated host computing devices eachimplementing independent and unrelated radio receivers may provideinformation indicating their respective availabilities to be contractedwith and/or used for various applications. As described herein, a clientdevice may contract with one or more host computing devices in order toutilize the radio receivers of the host computing devices. For example,a client device may contract with one or more host computing devices inorder to implement an application using the radio receivers (e.g., asignal strength map application, a transmitter location identificationapplication, a radio audio streaming application, and/or other type ofapplication that uses radio receivers).

As described herein, a blockchain, peer-to-peer network, and/or similartechnique may be used to provide host computing device information(e.g., information identifying the availability of host computingdevices and their respective radio receivers to be contracted). That is,the providing of host computing device information may be decentralized,and the blockchain may be a decentralized shared database of hostcomputing device information. A client device may discover a hostcomputing device from the blockchain in order to establish a contractingrelationship with the host computing device. As described herein, theblockchain may be used to facilitate the financial transaction betweenthe client device and the host computing device in connection with theclient device contracting with the host computing device for use of theradio receiver. Advantageously, the use of scattered, unrelated, andindependent radio receivers can be coordinated for various applications,such as radio spectrum analysis (e.g., signal strength mapping),transmitter localization, audio streaming, or the like.

Aspects of the present invention provide a technical solution to thetechnical problem of coordinating the use of scattered, unrelated, andindependent radio receivers. For example, aspects of the presentinvention include a system and/or method to provide consolidated hostcomputing device information (e.g., via a blockchain) which identifiesradio receivers associated with a single transmitter that can becontracted and used for a particular application (e.g., localizing atransmitter, identifying received signal strengths of the transmitter atvarious geographic locations, streaming audio from a radio station,etc.). Further, aspects of the present invention provide a technicalsolution to the technical problem of producing a signal strength map.For example, aspects of the present invention include a system and/ormethod to receive signal strength information from various unrelatedradio receivers in a geographic area, and associate the signal strengthinformation with geographic location information from which a signalstrength map can be generated. Further, aspects of the present inventionprovide a technical solution to the technical problem of localizing atransmitter. For example, aspects of the present invention include asystem and/or method to receive signal information from variousunrelated radio receivers, and use the received signal information toidentify the location of a transmitter using triangulation techniques.Further, aspects of the present invention provide a technical solutionto the technical problem of receiving audio radio signals from atransmitter (e.g., radio station) that is outside of its communicationsrange. For example, aspects of the present invention include a systemand/or method to receive audio radio signals, and stream the audio to aregion outside of the communications range.

It is understood in advance that although this disclosure includes adetailed description on cloud computing, implementation of the teachingsrecited herein are not limited to a cloud computing environment. Rather,embodiments of the present invention are capable of being implemented inconjunction with any other type of computing environment now known orlater developed.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g. networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based e-mail).The consumer does not manage or control the underlying cloudinfrastructure including network, servers, operating systems, storage,or even individual application capabilities, with the possible exceptionof limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forload-balancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.

Referring now to FIG. 1, a schematic of an example of a cloud computingnode is shown.

Referring back to FIG. 1, the Program/utility 40 may include one or moreprogram modules 42 that generally carry out the functions and/ormethodologies of embodiments of the invention as described hereinincluding functionality of the radio receiver application processing 96of FIG. 3. Specifically, the program modules 42 may discover hostcomputing devices, provide proposals to use radio receivers on the hostcomputing devices, and receive application data related to anapplication that uses the radio receivers of the host computing devices.Other functionalities of the program modules 42 are described furtherherein such that the program modules 42 are not limited to the functionsdescribed above. Moreover, it is noted that some of the modules 42 canbe implemented within the infrastructure shown in FIGS. 1-3. Forexample, the modules 42 may be representative of a client device and/ora host computing device as shown in FIG. 4.

FIGS. 4 and 5 show an overview of an example implementation inaccordance with aspects of the present invention. As shown in FIG. 4,environment 400 may include a client device 210, a host computing device215, a radio receiver 220, a transmitter 225, a blockchain network 230,and a network 240. Client device 210 and host computing device 215 mayinclude one or more of the components of computing system/server 12 ofFIG. 1, such as one or more program modules 42. Further, client device210 may include a radio receiver contracting module 212, which mayinclude one or more program modules 42 that perform one or morefunctions of the client device 210 as described below. In embodiments,the host computing device 215 may include a radio receiver hostingmodule 218, which may include one or more program modules 42 thatperform one or more functions of the host computing device 215 asdescribed below.

As shown in FIG. 4, the host computing device 215 may implement a radioreceiver 220 that receives radio signals from a single transmitter 225.The client device 210 and the host computing device 215 may communicatewith a blockchain network 230. The blockchain network 230 may include apeer-to-peer network via which a blockchain (e.g., a shared database) isexchanged and synchronized between participants of the blockchainnetwork 230. For example, the participants of the blockchain network 230may include any type of computing device that is capable ofcommunicating via a computing network. In the example of FIG. 4, theclient device 210 and the host computing device 215 may be participantsof the blockchain network 230, and thus, the client device 210 and thehost computing device 215 may each store or access the same blockchain.As described herein, the blockchain may include host computing deviceparticipation information in which host computing devices that areavailable for contracting are identified in the blockchain.

At step 1.1, the client device 210 may discover the host computingdevice 215 from the blockchain. For example, the client device 210 mayfilter the blockchain to identify host computing devices that meetparticular criteria (e.g., contracting/pricing criteria, applicationcompatibility criteria, radio operating frequency criteria, geographiclocation criteria, an identifier of a transmitter from which radiosignals are received, etc.). In embodiments, the client device 210 mayfilter the blockchain based on real-time user input of filteringcriteria. Additionally, or alternatively, the client device 210 mayautomatically filter the blockchain based on preconfigured criteria(e.g., each time radio receiver services are needed from a hostcomputing device).

At step 1.2, the client device 210 may provide an application code forexecution on the host computing device 215. For example, the clientdevice 210 may provide the application code via a network 240 (e.g., anexternal network such as the Internet, a virtual private network (VPN),cellular network, etc.). Alternatively, the client device 210 mayprovide an instruction for the host computing device 215 to obtain theapplication code from another source. As described herein, theapplication code includes instructions for the host computing device 215to process and/or provide data relating to radio signals received by itsradio receiver 220 from the transmitter 225. For example, theapplication code may relate to a signal strength mapping application, atransmitter localization application, a radio audio streamingapplication, etc. In embodiments, the host computing device 215 mayreceive the application code, and may validate and/or authenticate theapplication code (e.g., to ensure that the application code is receivedfrom an authorized device and does not include malicious and/orhazardous code). For example, the host computing device 215 mayauthenticate the code using any combination of authentication,encryption, decryption, and/or other techniques. As an example, athird-party cryptographic signing authority and/or service may be usedto verify that a signature of the application code is associated theclient device 210.

After receiving and authenticating the application code, at step 1.3,the host computing device 215 may execute the application code, and atstep 1.4 the host computing device 215 may provide application data tothe client device 210. The application data may include data relating tothe executed application. As an example, the host computing device 215may execute the application code to provide the client device 210 withapplication data including information identifying the signal strengthof a received signal at the geographic location of the host computingdevice 215. For example, the host computing device 215 may execute theapplication code to tune the radio receiver 220 to a particularfrequency at which the transmitter 225 is transmitting, receive theradio signals transmitted by the transmitter 225, and provide theapplication data. The client device 210 may use the application data togenerate a signal strength map (e.g., by consolidating signal strengthinformation and geographic location information from multiple differenthost computing devices 215 at different geographic locations). Inembodiments, the client device 210 may use the application data frommultiple different host computing devices 215 to geographically locatethe transmitter 225 using triangulation techniques (e.g., for a “rogue”transmitter that may be transmitting radio signals via an unauthorizedfrequency). In this way, information from independent and unrelatedradio receivers that each reactive radio signals from a singletransmitter can be coordinated in a simple and effective manner.

In embodiments, the client device 210 may store, output, or display theapplication data (step 1.5). For example, the client device 210 maydisplay the application data in the form of a map (e.g., a signalstrength map), a chart, a graph, or other format. In embodiments, theapplication data may include audio data which may be output via aspeaker of the client device 210 (e.g., for a radio audio streamingapplication). In embodiments, the client device 210 may output theapplication data to another device. For example, the client device 210may be a cloud server that may store the application data for access byan external device.

Referring to FIG. 5, information from a blockchain 250 may be used tofacilitate a financial transaction in connection with contracting thehost computing device 215 for use of the radio receiver 220. Forexample, at step 2.1, the client device 210 may discover the hostcomputing device 215 (e.g., in a similar manner as described above withrespect to step 1.1 of FIG. 4). At step 2.2 the client device 210 mayoutput a radio usage proposal that identifies the terms under which hostcomputing device 215 may be contracted for use of the radio receiver220. For example, the radio usage proposal may identify the applicationto be executed, the length of service, the type of service, pricinginformation, etc. At step 2.3, the host computing device 215 may providean acceptance of the proposal thereby establishing a contractingrelationship between the client device 210 and the host computing device215. For example, the contracting relationship may be established byestablishing a peer-to-peer connection between the client device 210 andthe host computing device 215. At step 2.4, the client device 210 maywrite transaction information to the blockchain 250 that effectuates atransfer of funds from an account of the client device 210 to an escrowaccount (e.g., a trusted escrow account between parties associated withthe client device 210 and the host computing device 215). Inembodiments, the client device 210 may write transaction information tothe blockchain 250 via a mining service.

At step 2.5, the client device 210 may provide the application code tothe host computing device 215, and the host computing device 215 mayexecute the application code (at step 2.6) and provide application data(at step 2.7) to the client device 210 (e.g., in a similar manner as isdiscussed above with respect to steps 1.2., 1.3, and 1.4 of FIG. 4). Atstep 2.8, the client device 210 may write transaction information to theblockchain 250 (e.g., when the client device 210 receives theapplication data from the host computing device 215), that effectuates atransfer of funds from the escrow account to an account of the hostcomputing device 215. At step 2.9, the client device 210 may store,display, or output the application data (e.g., in a similar manner asdescribed above with respect to step 1.5 of FIG. 4).

As described above, independent and unrelated host computing devices 215each implementing independent and unrelated radio receivers 220 mayprovide information indicating their respective availabilities to becontracted with and/or used for various applications. As describedherein, a client device 210 may contract with one or more host computingdevices 215 in order utilize the radio receivers 220 of the hostcomputing devices 215. In embodiments, a contracted host computingdevices 215 may obtain and execute an application or code container inorder to provide the client device 210 with a service relating to theuse of the radio receiver 220.

As an example, contracted host computing devices 215 may execute anapplication which directs the contracted host computing devices 215 tooutput information regarding respective signal strengths for receivedsignals transmitted by a particular transmitter within a particulargeographic area. The client device 210 may use the signal strengthinformation to generate a signal strength map identifying the signalstrength of a received transmitter signal at various geographiclocations within the geographic area. As another example, the clientdevice 210 may use signal strength information from various radioreceivers 220 to triangulate and locate the source of a particulartransmitter (e.g., a “rogue” transmitter that is transmitting signals onan unauthorized frequency). As another example, a contracted hostcomputing devices 215 may execute an application that directs the hostcomputing devices 215 to provide audio from a single transmitter (e.g.,a radio station) to the client device 210. The client device 210 mayitself play the audio, or stream the audio to another device. In thisway, the client device 210 may play the audio or stream the audio from aradio station outside of communications range.

As described herein, a blockchain, peer-to-peer network, and/or similartechnique may be used to provide host computing devices 215 information(e.g., information identifying the availability of host computingdevices 215 and their respective radio receivers 220 to be contracted).That is, the providing of host computing devices 215 information may bedecentralized, and the blockchain may be a decentralized shared databaseof host computing devices 215 information. The host computing devices215 information may identify the types of radio receivers 220implemented by the host computing devices 215, operating frequencies ofthe radio receivers 220, applications that the host computing devices215 may implement, etc. A client device 210 may discover a hostcomputing device 215 from the blockchain, and may filter the blockchainto identify host computing devices 215 that meet certain criteria basedon a desired application. For example, if the client device 210 is to beused to identify received signal strengths from a particular transmitterwithin a particular geographic area, the blockchain may be searchedand/or filtered to identify host computing devices 215 that implementradio receivers 220 within the particular geographic area and receivesignals from a particular transmitter. Further, the host computingdevices 215 information may identify pricing terms, service levelagreements, and/or other contracting terms. The client device 210 may beused to filter host computing devices 215 based on the contractingterms.

As described herein, a blockchain may be used to facilitate thefinancial transaction between the client device 210 and the hostcomputing devices 215 in connection with the client device 210contracting with the host computing devices 215 for use of the radioreceiver 220. For example, the client device 210 may provide a proposalto the host computing devices 215. In embodiments, a user of the clientdevice 210 may provide user input via a user interface to select andprovide proposals to host computing devices 215. Alternatively,proposals may be sent without user interaction (e.g., based on anautomated technique in which the client device 210 automaticallycontracts with host computing devices 215 to execute an application. Theproposal may include an offer to contract the host computing devices 215to execute an application based on radio signals received by the radioreceiver 220 (e.g., a signal strength application, a transmitterlocation triangulation application, a radio audio playback application,etc.). The proposal may include a price for contracting the hostcomputing devices 215, and/or other contracting terms.

In embodiments, the host computing devices 215 may receive and acceptthe proposal. For example, the host computing devices 215 mayautomatically accept the proposal if the proposal adheres topreconfigured policies (e.g., pricing policies, usage policies, etc.).Alternatively, a user of the host computing devices 215 may receive theproposal via a user interface of the host computing devices 215, and mayprovide user feedback to accept the proposal. When a proposal isaccepted, the client device 210 may write transaction information to theblockchain that effectuates a transfer of funds from an account of theclient device 210 to an escrow account. The host computing devices 215may then provide the contracted service to the client device 210 (e.g.,by executing an application or code for the client device 210). Theclient device 210 may write transaction information to the blockchain(e.g., when the client device 210 receives the application data from thehost computing device 215). Advantageously, the use of scattered,unrelated, and independent radio receivers 220 can be coordinated forvarious applications, such as radio spectrum analysis (e.g., signalstrength mapping), transmitter localization, audio streaming, or thelike.

The steps of FIG. 6 may be implementedin the environments of FIGS. 4 and 5, for example, and are describedusing reference numbers of elements depicted in FIGS. 4 and 5. As notedabove, the flowchart illustrates the architecture, functionality, andoperation of possible implementations of systems, methods, and computerprogram products according to various embodiments of the presentinvention.

As shown in FIG. 6, process 600 may include discovering a host computingdevice from a decentralized shared database (step 610). For example, theclient device 210 may discover a host computing device 215 from adecentralized shared database, such as a blockchain (e.g., in a similarmanner as described above with respect to step 1.1 and 2.1 of FIG. 4 andFIG. 5, respectively).

Process 600 may also include providing a radio usage proposal (step 620)and receiving acceptance of the proposal (step 630). For example, theclient device 210 may provide a radio usage proposal and receiveacceptance of the proposal (e.g., in a similar manner as described abovewith respect to step 2.2 and step 2.3 of FIG. 5). In embodiments, theradio usage proposal may include a request to access the host computingdevice 215 and a request to access data related to the radio signalsreceived by the radio receiver 220 of the host computing device 215. Theacceptance of the proposal may include an indication that the request toaccess has been granted.

Process 600 may also include establishing a contracting relationshipwith the host computing device 215 (step 640). For example, the clientdevice 210 may establish a contracting relationship with the hostcomputing device based on receiving the acceptance of the proposal(e.g., in a similar manner as described above with respect to step 2.2and step 2.3 of FIG. 5).

Process 600 may further include writing transaction information to fundan escrow account (step 650). For example, the client device 210 maywrite transaction information to the blockchain 250 to fund the escrowaccount (e.g., in a similar manner as described above with respect tostep 2.4 of FIG. 5). Process 600 may also include providing applicationcode (step 660). For example, the client device 210 may provide theapplication code to the host computing device 215 (e.g., in a similarmanner as described above with respect to step 1.2 and step 2.5 of FIGS.4 and 5, respectively).

Process 600 may further include receiving application data (step 670).For example, the client device 210 may receive the application data fromthe host computing device 215 (e.g., as described above with respect tosteps 1.4 and 2.7 of FIGS. 4 and 5, respectively). Process 600 may alsoinclude storing, outputting, or displaying the application data (step680). For example, the client device 210 may store, output, or displaythe application data (e.g., in a similar manner described above withrespect to steps 1.5 and 2.10 of FIGS. 4 and 5, respectively). Process600 may further include writing transaction information to transferfunds from the escrow account to the house computing device account(step 690). For example, the client device 210 may write the transactioninformation to the blockchain 250 to effectuate a transfer of funds fromthe escrow account to the house computing device account (e.g., in asimilar manner described above with respect to step 2.8 of FIG. 5).

FIG. 7 shows an example implementation for coordinating the use ofmultiple unrelated radio receivers to generate a signal strength map inaccordance with aspects of the present invention. As shown in FIG. 7,radio receivers 220-1 through 220-N (where N is greater than or equal to1) may receive radio signals from a single transmitter (e.g. thetransmitter 225). In the example of FIG. 7, the client device 210 hascontracted with host computing devices 215-1 through 215-N for receivingsignal strength information from host computing devices 215-1 through215-N (e.g., based on the processes described herein). The hostcomputing devices 215-1 through host computing device 215-N may provideapplication data to the client device 210 in which the application dataincludes signal strength information and location information for eachof host computing devices 215-1 through host computing devices 215-N.The host computing device 215 may receive the application data, and maygenerate a signal strength map (as shown interface 700) that identifiesthe signal strengths for signals transmitted by the transmitter 225 andreceived by the host computing devices 215 at the locations of the hostcomputing devices 215. In the example of FIG. 7, each circle on the mapindicates the received signal strength by each radio receiver 220 at aparticular geographic location. Each circle may be colored or shadedsuch that different colors and shaded represent different signalstrengths (e.g., darker shades represent stronger signal strengths). Inthis way, a signal strength map can be generated using host computingdevices 215 that are unrelated to each other. In embodiments, an owneror administrator of the transmitter 225 may use the signal strength mapto identify geographic areas in which signal reception strength isrelatively low. The signal strength map may be used to modify thetransmitter 225 such that signal reception is improved in areas in whichsignal reception strength is relatively low. As described herein, theclient device 210 may provide the application data to another devicewithout itself displaying the signal strength map.

Asshown in FIG. 8, radio receivers 220-1 through 220-N (where N is greaterthan or equal to 1) may receive radio signals from a single transmitter(e.g. a portable transmitter 225 as opposed to a fixed transmitter as inthe preceding examples). The client device 210 may contract with thehost computing devices 215-1 through 215-N to receive informationidentifying the signal reception strength at various geographiclocations for signals received from the transmitter 225. In a similarmanner as described above in FIG. 7, the host computing devices 215-1through 215-N may provide application data to the client device 210 inwhich the application data includes information identifying the signalreception strength at various geographic locations. The client device210 may use the application data to generate a signal strength map andmay further identify a possible location of the transmitter 225 usingtriangulation techniques. In embodiments, the client device 210 maydisplay the signal strength map and the possible location. Additionally,or alternatively, the client device 210 may provide the application datato another device so that the other device may be used to display thesignal strength map and/or possible location of the transmitter 225.

FIG. 9 shows an example implementation for accessing an independentradio receiver by a client device for receiving radio audio from atransmitter outside of communications range of the client device inaccordance with aspects of the present invention. As shown in FIG. 9,radio receiver 220 may receive audio radio signals from a transmitter225 (e.g., a radio station). In the example illustrated in FIG. 9, theclient device 210 has contracted with host computing device 215 forreceiving radio audio from the host computing device 215 (e.g., based onthe processes described herein). The host computing device 215 mayprovide the radio audio to the client device 210, and the client device210 may output the radio audio through a speaker of the client device210. In embodiments, the application code, associated with the clientdevice 210, may cause the host computing device 215 to convert the radioaudio into a format that can be streamed to the client device 210 via anIP network. In embodiments, the client device 210 may provide the radioaudio to another device without the client device 210 itself outputtingthe radio audio.
